The genotype is the part of the genetic makeup of a cell, and therefore of an organism or individual, which determines one of its characteristics . The term was coined by the Danish botanist, plant physiologist and geneticist Wilhelm Johannsen in 1903.
Learning modalities are the sensory channels or pathways through which individuals give, receive, and store information. Perception, memory, and sensation comprise the concept of modality. The modalities or senses include visual, auditory, tactile/kinesthetic, smell, and taste.
One way to classify sensory structures is by the stimuli to which they normally respond; thus, there are photoreceptors (for light), mechanoreceptors (for distortion or bending), thermoreceptors (for heat), chemoreceptors (e.g., for chemical odours), and nociceptors (for painful stimuli).
